- Parameterized by `lookback` (default 5).
- Output range: Varies (see docs).
- Requires 1 bar of warmup before first valid output (IsHot = true).
- **Similar:** [Fractal](../../oscillators/fisher/Fisher.md), [ZigZag](../psar/Psar.md) | **Complementary:** Volume for confirmation | **Trading note:** Swing high/low detector; identifies pivots for support/resistance and chart pattern analysis.
- Validated against TA-Lib, Skender, and Tulip reference implementations where available.
Swing High/Low detection identifies local price extremes using a configurable lookback window. A Swing High marks a bar whose high strictly exceeds the highs of all bars within the lookback window on each side. A Swing Low marks a bar whose low is strictly less than all corresponding lows. The lookback parameter controls sensitivity: larger lookback windows require more confirmation and produce fewer, more significant signals. This generalizes Williams' fixed five-bar Fractals into a flexible structural analysis tool.
